A system includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to receive a plurality of doubly-encrypted secret parts that were encrypted using at least a public key belonging to a public/private keypair. The at least one processor is also configured to decrypt each of the plurality of doubly-encrypted secret parts into a corresponding singly-encrypted secret part using a private key belonging to the public/private keypair. The at least one processor is also configured to decrypt each corresponding singly-encrypted secret part into a corresponding secret part. A secret is reconstructed from a quantity of corresponding secret parts that is a subset of a total number of secret parts. The public key, the private key, or both are rotated by creating a new version of the public key, the private key, or both.

In an example, a system comprises at least one processor, at least one memory communicatively coupled to the processor, and at least one network interface communicatively coupled to the processor. The processor is configured to: receive an intent to purchase a token into a transaction address from a remote computing device; receive signed data, signed by a private key, from the computing device; receive at least one of the transaction address or public key associated with the transaction address from the computing device; verify that the transaction address or the public key is associated with the private key; verify that the transaction address or the public key is whitelisted to purchase the token; and allow purchase of the token into the transaction address when the target transaction address or the public key is both: (1) associated with the private key and (2) whitelisted to purchase the token.

Verifying transaction address is whitelisted before allowing transfer to transaction address of self-regulating token requiring whitelisted transaction address to withdraw self-regulating token

A computerized method includes receiving payment of an amount of cryptocurrency from a transaction account to another account.

A system includes: a plurality of network nodes communicatively coupled in a peer-to-peer network; and a plurality of computing devices each communicatively coupled to at least one of the plurality of network nodes.

A second subset of network nodes (including at least two network nodes) match the plurality of market trade requests.

When encryption key(s) need to be used, processor(s): receive set(s) of key components from subset(s) of users that can be used to reconstruct encrypted key and encryption key(s) used to decrypt key from encrypted key; when set(s) of key components is received from subset(s) of users that can be used to reconstruct encrypted key and encrypted key(s), reconstruct encrypted key and encryption key(s); and when the encrypted key and the encryption key(s) have both been reconstructed, decrypt encrypted key into key using encryption key(s).
